Rumour has it that the Pixel 5 will not be the successor to the compact Pixel 4. Instead, the device will be closer to the size of the Pixel 4 XL, which points towards it having a 6.67-inch and 120 Hz display. A US$699 starting price has been suggested too, but Google will only be offering a Snapdragon 765G and a capacitive fingerprint scanner for your money.
